Laser Cutting Machine In Indore

Choosing a Laser Cutting Machine in Indore: Five Configurations

A fiber laser cutting machine for metal is chosen first by how your work arrives: mixed one-off jobs, repeat batches, a shared shop floor, sheet plus tube, or mostly tube. In laser cutting, Sigma makes only fiber laser cutting machines, and the range covers each of those five situations:

On the auto pallet changer, one pallet is loaded while the other cuts, which earns its cost on long runs of the same part and much less on short, changing jobs. The close body machine has an enclosed cabin with interlocked doors and built-in dust and fume extraction. The tube attachment handles round, square and rectangular tube.

Flat-bed machines come on six standard beds from 3200 x 1600 mm to 6500 x 2500 mm. Pick the bed from the sheet size you buy and the largest part you cut. If no standard bed fits, Sigma engineers a bed to your drawing. The frame, bed and structure of each machine are made at Sigma’s Ahmedabad plant, components are selected and integrated by Sigma’s engineers, and every build is inspected stage by stage. Every configuration is on Sigma’s laser cutting machines page.

Which Laser Power Should You Buy?

Laser power should match the material and thickness you cut on most days, not the heaviest job you see a few times a year. Power decides how thick a sheet the machine can cut and how fast it cuts each thickness.

If most of your work is thin sheet and thick plate arrives now and then, buying for the plate means paying for capacity that sits idle most of the week. Buying for the daily mix keeps the cost tied to the work that earns money, but the occasional thick job then goes out as job work. Neither choice is wrong; it depends on how often that heavy job returns and what it is worth. List your last three months of jobs by material and thickness before you shortlist a power, and send that list with your enquiry.

The machines cut mild steel, stainless steel and aluminium as standard. Brass and copper reflect much of the laser beam back towards the machine, so they are cut with a cutting head protected against back-reflection; tell Sigma at the enquiry stage if they are part of your work.

Features That Keep the Machine Cutting

The features that matter on a fiber laser cutting machine are the ones that cut setting-up time and protect the head, because those decide how much of a shift goes into cutting. Sigma’s fiber laser cutting machines have:

• Auto edge finding. The machine locates the sheet’s edge and angle and aligns the program to it, so nobody squares the sheet by hand and less of the sheet is wasted at the edges.
• Fly cutting. Rows of holes and small shapes are cut in one continuous pass without lifting the head between them, which saves idle travel on perforated and repetitive parts.
• Anti-collision cutting head. The head is protected if it meets a part that has tipped up after cutting, which limits damage and downtime.
• Auto height following. Capacitive sensing holds a constant gap between the nozzle and the sheet, even on slightly bowed sheet, so focus and cut quality stay consistent.
• Drawing import and nesting. The CNC takes DXF and DWG files and nests parts on the sheet to reduce scrap.

Basic Technical Data: 1.5 kW and 3 kW

A technical data sheet shows what the laser power, table and motion of a machine can do, and two quotations can be compared only when their data belongs to the same laser power and bed size. Basic technical data for Sigma’s 1.5 kW and 3 kW fiber laser cutting machines:

Linked speed is how fast the head travels between cuts with the axes moving together, and acceleration is how quickly it reaches that speed. Neither is the cutting speed, which depends on laser power, material and thickness, so ask for cutting speed on your own material at the power quoted. The 3 kW machine’s 1 G acceleration matters most on parts with many small holes and short cuts, where the head rarely reaches top speed.

Positioning and repositioning accuracy describe the machine’s motion, not the tolerance of a finished part. Part tolerance also depends on the kerf (the width of metal the beam removes), the material, the thickness and the cutting parameters, so judge it on parts cut in front of you.

See a Machine of Your Power Cutting in Indore

A live demo is worth your time only when the machine you watch has the laser power you plan to buy. Sigma arranges a free live demo in Indore on a machine of that power, running at a site where Sigma has installed one: if you plan to buy a 3 kW machine, you watch an installed 3 kW machine cutting. A machine on a working floor shows how it runs day to day, with its operator, on real jobs.

What to check during the demo:

• The material and thickness being cut, and how close they are to your daily work.
• The cut edge: dross (re-solidified metal clinging to the underside), burr (a sharp raised lip along the cut), and how even the edge face looks along its length.
• Small holes and sharp corners, which show how well the motion and the cutting parameters are tuned.
• How a drawing becomes a cutting program: importing the file, nesting the parts and starting the job.
• How the sheet is loaded and aligned, and how fume is extracted during cutting.

Take a drawing of a typical part, so the demo stays on your work.

Installation, Training and Service at Your Indore Premises

Buying from Ahmedabad changes where the machine is built, not where it is installed and serviced. Sigma’s own team installs and commissions the machine at your premises in Indore, sets the cutting parameters on your material and trains your operators on your machine with your own jobs. Installation and 1 to 7 days of operator training are free.

Your side of the installation is the site, and commissioning cannot start until it is ready:

• Floor and handling. Plan the crane or forklift, the route in and the floor the machine will stand on, using the weight in the data above.
• Electrical supply. Check that your sanctioned load leaves room for the machine alongside everything else in the shed, and ask whether a stabiliser is advised if the voltage in your area fluctuates.
• Air, gas and extraction. Compressed air, the assist gas that blows molten metal out of the cut (usually oxygen or nitrogen), and space for fume extraction.

Put at least two people through the training, including whoever will program and nest the parts, so production does not depend on one operator.

After installation, service is handled directly by Sigma’s own technical team, not a dealer or agent, with 24/7 support. Get these terms written into the quotation:
